Elasto-Plastic Analysis of Stress and Strain Concentration by the Combination of Body Force Method and Finite Element Method
A numerical method based on the combination of the body force method (BFM) and the finite element method (FEM) is developed for the elasto-plastic analysis of the problems in which the plastic regions are small in comparison with other elastic regions.
The usefulness of the method is demonstrated by the analysis of stress-strain concentration at a circular or an elliptical hole in an infinite plate. The accuracy of Neuber’s rule is discussed on the basis of the numerical results.
